CTAN update: xint
Date: August 2, 2017 10:09:29 AM CEST
Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.2m 2017-07-31
License type: lppl1.3c
Summary description: Expandable operations on long numbers
Announcement text:
All macros of xintbinhex.sty have been rewritten using techniques from the 1.2 release (they had remained unmodified since 1.08 of 2013/06/07.) The new macros are faster but limited to a few thousand digits. The 1.08 routines could handle tens of thousands of digits, but not in a reasonable time. A few more modest improvements; and bugfix of the bookmarks in the PDF documentation.
This package is located at http://mirror.ctan.org/macros/generic/xint More information is at http://www.ctan.org/pkg/xint
Thanks for the upload. For the CTAN Team Manfred Lotz We are supported by the TeX user groups. Please join a users group; see http://www.tug.org/usergroups.html .

xint – Expandable arbitrary precision floating point and integer operations
The xint bundle main modules are:
- xinttools
- utilities of independent interest such as expandable and non-expandable loops,
- xintcore
- expandable macros implementing addition, subtraction, multiplication, division, and powers for arbitrarily long integers,
- xint
- extension of xintcore,
- xintfrac
- extends the scope of xint to decimal numbers, to numbers using scientific notation and also to (exact) fractions,
- xintexpr
- provides expandable parsers of numeric expressions using the standard infix notations, parentheses, built-in functions, user definable functions and variables (and more ...) which do either exact evaluations (also with fractions) or floating point evaluations under a user chosen precision.
Further modules of the bundle are:
xintkernel (support macros for all the bundle constituents),
xintbinhex (conversion to and from hexadecimal and binary bases),
xintgcd (provides gcd() and lcm() functions to xintexpr),
xintseries (evaluates numerically partial sums of series and
power series with fractional coefficients), and
xintcfrac (dedicated to the computation and display of continued fractions).
All computations are compatible with expansion-only context.
The packages may be used with Plain TeX, LaTeX, or (a priori) any other macro format built upon TeX.
